I confess: I am a saltaholic. I salt almost all my foods (yes, usually before even tasting) 
and crave salty/crunchy snacks, like pretzels and peanuts.
You hear and read all the medical people saying, as you get older, you should really limit your salt intake because it is bad for you.
But my blood pressure is low and, more importantly, I really sweat and deplete my system of salt and electrolytes on hot tennis days. In “the old days,” they actually used to give athletes salt pills to take on hot days.
So, you knowledgeable people… limit the intake or “listen to your body”???
The running experts say that the more salt you take in the more you will sweat. Eat your chips after your match bill
The relationship between salt, fluid levels in the body and blood pressure was highlighted recently in a study published on-line in the journal Hypertension [1]. In this study, individuals were put at different times on low and high sodium diets, each for a period of a week. These individuals were all suffering from what is termed ‘resistant’ hypertension. Which means that despite multiple medications, the blood pressure remains high. The average number of medications taken by participants in this trial was 3-4. Average blood pressure was 146/84 mmHg.
The high sodium diet contained 5.75 grams of sodium (about 14.5 grams of salt) a day. The low sodium diet contained 1.15 grams of sodium (about 2.9 grams of salt) a day.
Compared to the high salt diet, the low-salt diet reduced blood pressure significantly: the systolic (higher) and diastolic (lower) blood pressure dropped by about 23 and 9 mmHg respectively. Chemical analysis of the blood revealed that this was most likely due to a reduction in blood (plasma) volume.
Those with raised or borderline raised blood pressure may like to consider cutting back on salt. 80-90 per cent of the salt consumed in the Western diet comes from processed foods, some of which are extremely salty but don’t necessarily taste it. For example cornflakes, gram for gram, contain as much salt as seawater. Processed food is the place to look to effectively cut down on salt intake. After that, we might consider limiting what we add during cooking and at the table too.
Another nutritional approach to combating high blood pressure is to increase intake of potassium (found, for example, in fruits and vegetables).
